The WISY filter collector captures rainwater for use in the home, enabling households
to save up to 50% of their mains water consumption. It is a highly efficient
self-cleaning device which is fitted directly into rainwater downpipes. It captures
over 90% of the rainwater from the down-pipe, filtering it and diverting it into
a storage tank. The remaining water carries leaves and other debris from the
roof straight down into the drains.

The simple but high precision WISY Filter Collector uses surface tension in conjunction
with an ultra-fine filter mesh to remove all particles larger than 0.28 mm.

The standard filter is easily fitted by cutting out a section of down-pipe
and replacing this with the filter. The system ensures that there is no contamination
and little risk of blockages.

The high-grade stainless steel housing of the Filter Collector is non-rusting
and frost resistant. Zinc and copper housings are also available.

The Filter Collector can be used in conjunction with most roofing systems.
Ideally collecting roofs should be of tile or slate: asbestos or heavily soiled
roofs should not be used for rainwater collection.

Since their invention in Germany in 1989, WISY filters have been successfully
installed in over 100,000 homes. A rainwater harvesting system is increasingly
becoming a standard feature in many new home developments not only on the Continent
but also in the UK.

Available in several sizes, two of which are specially designed for compatibility with UK standard 110mm and 68mm plastic pipes
